Query shortest path from ShortestPathSubgraph

[redbug312]

The hidden docs says there's a method to query shortest path from ShortestPathSubgraph,
but there's only a method distance_to presented.
It seems difficult to obtain the shortest path without information of prev. Is there a way to do this?

Also, the method distance_to returns Option<Magnitude<W>>.
I wonder if Magnitude<W> would be better, with Magnitude::PosInfinite replacing for None?

Hi,
Ah, I see how it can be confusing. The documentation means the distance between each pair of vertices.
I'm currently working on my thesis and unfortunately can not spend time on this project. But I'll look into it and if providing prev is relatively easy, I'll add it to the next version. Or if you're up to the task, A pull request is always welcome. :)

You're right. It'll be better. I'll implement it in the next version.
